The longest recorded freefall was over 4 minutes by Joe Kittinger, who jumped from 102,000 feet in the 1960s. The gravity of the Earth pulls at you with a constant acceleration of 9.81 meters/second. There is no initial velocity, and the only acceleration (directed downwards) is the acceleration of gravity g. From the definition of velocity, we can find the velocity of a falling object is v = g*t, where t stands for time. In non-SI units the acceleration due to gravity is approximately 32 feet per second 2. After two seconds we reach 64 feet per second. That's only if air drag is important. (adsbygoogle = window.adsbygoogle || []).push({}); The calculator uses the standard formula from Newtonian physics to figure out how long before the falling object goes splat: That point is called terminal velocity (see this wikipedia article for more information).
